An NPC named Robin has been found. WoWhead, asite that scours the game code for new additions, picked up three instances of the tribute in a recent update for the Warlords of Draenor beta build - a male human, a female human, and a blue genie.

This model has been used before as a boss in a dungeon, but the idea is that this version of the model will most likely transform into other Robin Williams' characters.
